| Summary: | The objective of this work was to describe the anatomical and pathological findings in female, long-lived Bubalus buba lis from Portuguesa state, Venezuela. The age of 10 females was determined using the dental chronometry technique. Rectal palpation was performed to detect pregnancy. The udder integrity was evaluated, and days open between pregnancies were calculated. The animals were sent to slaughter. The ages of buffaloes were between 9 and 19 years old, and none of them were pregnant. In addition, 30% presented anomalies in the nipples and had a mean of 252 days open. At the slaugh-terhouse, the organs were collected: lung, mediastinal lymph nodes, heart, liver, kidney, spleen, and uterus. A 10% buffered formaldehyde solution was used for fixing and transporting the tissues. Later on, histological slices and routine HE stains were performed for examination using an optical microscope. The observed lesions, in percentage (%), were the following: chronic lymphoproliferative pneumonia (60), chronic lympho-histiocytic hyperplastic pericarditis (90), concentric cardiac hypertrophy (90), sarcocystosis (20) and lymphoid hyperplasia in the mediastinal lymph node (40). In the spleen: hemosiderosis (40), hemorrhage (40), lymphoid depletion (40), chronic multifocal non- suppurative hepatitis (70). In the kidney: interstitial lymphoplasmacytic membrane-proliferative glomerulonephritis (60), polycystic kidney (40), parenchymal atrophy (40), and non-suppurative chronic interstitial nephritis (90). In the reproductive organs: mild non-suppurative chronic cervicitis (70), mild non- suppurative chronic endometritis with severe glandular atrophy (70), oviduct fibroplasia (50), ovarian atrophy (80) and persistent corpus luteum (20). Severe restrictive pericarditis, which led to cardiac remodeling as a progressive response to acute or chronic damage of an etiology not studied in this investigation, accompanied by hypertrophy of the ventricles, were changes in the organ’s shape that could have compromised its functioning. These anatomopathological findings in long-lived female Bubalus bubalis propose the need to study long-lived animals that are sacrificed or die naturally to obtain information on organ damage that can contribute to establishing the basis for the possible causes of low productivity and fertility. This species, considered resistant to tropical diseases, is resilient enough to survive up to 19 years, some with severe damage to vital organs. Finally, this research raises the need to keep productive, reproductive, and health records during the animal’s life, accompanied by results of routine tests carried out by qualified personnel.
